TMS in cognitive plasticity and the potential for rehabilitation.

Cognitive neuroscientists use transcranial magnetic stimulation (TMS) in several ways, from aiming to increase understanding of brain-behavior relationships to transiently improving performance, both in normals and in patients with neurological and neuropsychological deficits. Different types of TMS (single-pulse, paired-pulse, repetitive) are able to interfere with higher brain functions that require the cooperation of different brain areas and complex neuronal networks. Currently, behavioral TMS effects on the brain are usually short-lived and their underlying mechanisms not yet wholly understood. However, the aim of using TMS to develop rehabilitative strategies for motor, perceptive and cognitive functions represents an intriguing challenge.
